A LoRaWAN hub for places with no usable cell service. At festivals the cell network overloads and phones stop working, so our group carried LoRaWAN devices and this totem was the hub that kept us in touch.
HULL/20 | Flying Saucer
Fully interactive, app-controlled 7′ flying saucer that is scene and presence aware. 1,406 addressable LEDs on an Arduino Nano ESP32, hovering over the driveway: a camera notices visitors and the saucer reacts and the scenes run from my iOS app.
